The SC17 is only available with Windows 10 Home. You can however purchase an upgrade to Windows 10 Professional through the Windows 10 Store by going to Settings > Updates and Security > Activiation, and clicking the "Go to store" button.

Once upgraded, doing a System Recovery will reset Windows back to a clean install of Windows 10 Professional.

If you upgrade Windows and we have to restore your system back to Windows 10 Home during warranty service, you will need to apply your upgrade again, but you will not need to re-purchase the upgrade again.
